Subject: [Regression drm-tip] Internal audio device missing

Dear Linux folks,


With

     $ git describe --tags drm-tip/drm-tip
     v5.5-rc3-1481-ga20d8cd6901a

the internal audio device is not available, and just a dummy device.

Running `alsa-info.sh` [1], the messages below are shown with the 
problematic Linux kernel.

     alsactl: get_controls:567: snd_ctl_open error: Sound protocol is 
not compatible
     cat: /tmp/alsa-info.ateDlDjrZX/alsactl.tmp: No such file or directory

Please find the output of `alsa-info.sh` with Linux 5.5-rc3 and drm-tip 
attached.


Kind regards,

Paul
